A cross-sectional study evaluating patients' preferences for Salter innominate osteotomy.

BACKGROUND: Residual acetabular dysplasia in children after reduction of hip dislocation is often treated using Salter innominate osteotomy to prevent future osteoarthritis. Preventive surgery for asymptomatic patients, which could result in overtreatment, should be carefully applied with consideration of patients' opinions. In this study, we aimed to describe opinions on Salter innominate osteotomy as preventive surgery for children among adult patients who had undergone periacetabular osteotomy for hip pain due to hip dysplasia. METHODS: A mail-in questionnaire survey was conducted with 77 patients who underwent periacetabular osteotomy. Participants responded whether they would recommend Salter innominate osteotomy as preventive surgery for children and the reason for their opinion. We also performed a patient-based evaluation using the Japanese Orthopaedic Association Hip-Disease Evaluation Questionnaire and assessed clinical outcome measures with the Japanese Orthopedic Association score. Their recommendations and reasons were evaluated, and associations between their opinions and demographic and clinical characteristics were analyzed. RESULTS: Forty-three patients (56%) responded to the questionnaire. Of these, 10 (23%) patients recommended undergoing Salter innominate osteotomy, 28 (65%) patients did not, and 5 (12%) patients responded they were undecided. No significant association was observed between their opinions and demographic/clinical characteristics evaluated in the survey. The most frequent reason for why they do not recommend Salter innominate osteotomy was related to uncertainty about future hip pain. CONCLUSIONS: In total, 65% of the study participants did not recommend Salter innominate osteotomy for children with risk of dysplasia in the future. Participants' preferences regarding preventive surgery were not influenced by demographic and clinical characteristics.

[Preventive surgery after vascular reconstruction for chronic lower limb ischemia]. / Preventivnye khirurgicheskie vmeshatel'stva posle sosudistykh rekonstruktsii po povodu khronicheskoi ishemii nizhnikh konechnostei.

OBJECTIVE: To analyze the results of redo reconstructions of lower limb arteries in patients with obliterating atherosclerosis, immediate and long-term results in patients who underwent reconstructive interventions with occlusion of previous reconstruction and preventive interventions. MATERIAL AND METHODS: The study included 43 patients. The main group (group 1) consisted of 18 patients who underwent preventive vascular reconstructions. The control group enrolled 25 patients who underwent redo interventions for occlusion of previous reconstructions. The control group was divided into 2 parts; 15 patients had chronic limb ischemia (group 2), 10 patients had acute limb ischemia (group 3). Mean age of patients was 56.8±8.2 years; there were 37 (86%) men and 6 (14%) women. Multifocal vascular atherosclerosis was noted in 41 (95.3%) patients, carotid artery lesion - 29 (70.7%), coronary artery disease - 34 (79%). Patients with type II diabetes mellitus were excluded. RESULTS: We chose each surgical intervention considering preoperative diagnostic data. Open, endovascular and hybrid interventions were performed. There were no deaths and limb amputations in the 1st group. Two (13.3%) amputations were registered in the 2nd group, 3 (30%) amputations and 1 (10%) death were registered in the 3rd group. The follow-up period was 24 months. An 18-month freedom from amputations was 71.5%, 78% and 38%, respectively (p<0.05 compared to the 1st and 2nd groups). CONCLUSION: Preventive surgical interventions prevent ischemia and amputation, as well as improves the results of redo surgery.

Short-term and long-term outcomes after preventive surgery in adolescent patients with familial adenomatous polyposis.

BACKGROUND: APC gene pathogenic variants are characterized by a lifetime risk of nearly 100% to develop a colorectal carcinoma. International guidelines suggest a prophylactic surgery in the second decade. METHODS: A descriptive analysis was performed evaluating a surgical series of adolescent patients with familial adenomatous polyposis (FAP) enrolled in the prospectively maintained hereditary polyposis registry. RESULTS: Thirty-eight adolescent patients (median age 16 years; range, 7-19) underwent laparoscopic prophylactic surgery. APC gene pathogenic variants were detected in all patients, and six patients were proband. No patients were converted to open surgery. Median postoperative stay was five days (4-16). Early postoperative complications were one dural puncture and one anastomotic leakage. Regarding late complications, we observed one patient having small bowel obstruction 56 months after surgery. Pathological reports showed one patient with pTis adenocarcinoma in two separate sites; 33 patients with low-grade dysplasia, four with high-grade dysplasia. One patient developed a desmoid tumor 37 months after surgery. After a median follow-up of 40.5 months, no patients died or had a second abdominal surgery because of cancer in rectal stump. CONCLUSIONS: Rectal sparing surgery was the first choice in the major respect of patients' quality of life. Laparoscopic prophylactic surgery for FAP is well accepted from adolescents. It represents a safe option due to the low incidence of post-surgical desmoids and quick postoperative recovery.

Incidental diffuse low-grade gliomas: from early detection to preventive neuro-oncological surgery.

Although a large amount of data supports early surgical resection for symptomatic diffuse low-grade glioma, the therapeutic strategy is still a matter of debate regarding incidentally discovered diffuse low-grade glioma. Indeed, early and "preventive" surgery has recently been proposed in asymptomatic patients with silent diffuse low-grade glioma with better outcomes. The present review discusses the importance of an early diagnosis and of a preventive surgical treatment to improve the outcomes of incidental diffuse low-grade glioma and suggests the possible relevance of a tailored screening policy.

Therapeutic outcomes of laryngeal closure and laryngostomy in children with recurrent pneumonia.

PURPOSE: Children with medical complexity frequently experience difficulty breathing and swallowing and occasionally develop aspiration pneumonia. Long-term intubation may cause fatal trachea-innominate artery fistula (TIF). In the present study, we retrospectively evaluated the efficacy of laryngeal closure and laryngostomy in children with medical complexity. MATERIALS AND METHODS: Laryngeal closure and laryngostomy were performed in eight children with severe neuromuscular disorders who were incapable of oral ingestion and verbal communication. The laryngostoma was placed at a higher position compared to that in conventional tracheostomies for easier management of the airway and to prevent TIF. RESULTS: Aspiration was successfully prevented postoperatively in all cases. Laryngocutaneous fistula formation was not observed. Two patients successfully achieved oral ingestion capability and tracheal cannulas were removed in two patients. Among the six patients who needed a mechanical ventilator before surgery, two patients were weaned from mechanical ventilation. Five patients were successfully discharged from the hospital. Although two patients died because of their primary condition, pneumonia exacerbation was not observed in any of the patients. CONCLUSION: Compared to the conventional tracheostomy, our procedure improved airway management and function in children with medical complexity and reduced the risk of TIF.

Insights From the Analysis of Clinicopathological and Prognostic Factors in Patients With Gallbladder Cancer.

Aims: To investigate the clinical efficacy and prognostic factors of primary gallbladder cancer (GBC) treated by radical surgery. Methods: The clinical and pathological data of 168 patients with primary gallbladder cancer admitted and treated in the Third Affiliated Hospital of Soochow University from January 1st, 2010 to December 31st, 2018 were analyzed retrospectively. Kaplan Meier method was used to draw the survival curve and evaluate the survival rate. Chi-square test was used for univariate analysis and binary logistic regression was used for multivariate analysis. Results: 94 cases showed symptoms of abdominal pain and abdominal distension. 7 cases showed symptoms of fatigue and weight loss. Jaundice occurred in 10 patients. Fever occurred in 6 patients. 51 patients had no symptoms at all. The median survival time of 168 patients was 35.0 (1.0 ~ 142.0) months. The overall 1-, 2- and 3-year cumulative survival rates were 69.6%, 55.4% and 48.8% respectively. The univariate analysis indicated that preoperative bilirubin, tumor size, tumor location, pathological type, degree of differentiation, liver invasion, nerve invasion, vascular invasion, surgical margin, filtration depth and N staging were significant factors influencing prognosis of patients with primary GBC (P<0.05). The results of multivariate analysis demonstrated that degree of differentiation, nerve invasion, filtration depth and N staging were independent risk factors for prognosis of patients with primary GBC (P<0.05). Conclusion: Patients with risk factors of gallbladder cancer should be more active in early cholecystectomy to avoid the malignant transformation of benign diseases. Degree of differentiation, nerve invasion, filtration depth and N staging were important factors for poor prognosis of patients with primary GBC. For T4 staging patients, preoperative evaluation should be more comprehensive, and patients and surgeons should be more prudent in adopting appropriate clinical treatment. The primary purpose should be prolonging the survival time and improving the quality of life.

The effect of needle tenotomy on hammer, mallet and claw toe deformities in patients with diabetes, a retrospective study.

AIM: The aim of this study was to evaluate outcomes of needle tenotomies as a treatment option for hammer, mallet and claw toes in patients with diabetes. METHODS: This was a retrospective study where all patients receiving flexor tendon tenotomy by needle at our outpatient clinic were identified through the electronic patient record system. RESULTS: A total of 81 patients that had 106 tenotomy procedures performed were identified. The 81 included (68% male) had an average age of 65.4 years, and 27 (33%) had Type 1 diabetes. Of the 106 procedures 36 were performed due to an ulcer on the feet. Of the 36 treated ulcers, 34 (94%) healed in an average time of 28 days. Tenotomies performed to prevent impending ulcers from progressing to active ulcers, were performed 84 times in total. Of the 84 procedures 6 patients progressed to an active ulcer. No serious complications i.e. infections or amputations in relation to the procedure were registered. CONCLUSION: Needle flexor tenotomies are a relatively safe and effective treatment compared to tenotomies done by scalpel, both as treatment for ulcers and to prevent formation of new ulcers associated with hammer, mallet and claw toe deformities. As a side note, transfer lesions are avoidable if all toes on one or both feet are tenotomized in one procedure.

Development and validation of a nomogram predicting the probability of type a aortic dissection at a diameter below 55 mm: A retrospective cohort study.

INTRODUCTION: The study aims to build and validate a nomogram for estimating the probability of patients developing type A aortic dissection at a diameter less than 55 mm. METHODS: A primary cohort of 896 patients diagnosed with acute type A aortic dissection by computed tomography angiography (CTA) were used for model development, with data collected between January 2005 and March 2012. The subjects were assigned to two groups based on ascending aorta diameter (group A<55 mm, Group B ≥ 60 mm). Univariate and multivariate logistic regression analyses were employed for the development of the prediction model. Demographic factors, as well as clinical and imaging characteristics were taken into account. The resulting nomogram was evaluated for performance traits, e.g. calibration, discrimination and clinical usefulness. After internal validation, the nomogram was further assessed in a different cohort containing 385 consecutive subjects examined between January 2013 and December 2015. RESULTS: The individualized prediction nomogram included 9 predictors derived from univariate and multivariable analyses, including gender, age, weight, hypertension, liver cyst, renal cyst, bicuspid aortic valve, and bovine arch. Those predictors were double confirmed with Lasso regression. Internal validation showed good discrimination of the model with area under the curve (AUC) of 0.854 and good calibration (Hosmer-Lemeshow test, P = 0.876). Application of the nomogram in the validation cohort still revealed good discrimination (AUC = 0.802) and good calibration (Hosmer-Lemeshow test, P = 0.398). Decision curve analysis demonstrated that the prediction nomogram was clinically useful. CONCLUSIONS: The current work presents a prediction nomogram incorporating demographical data as well as clinical and imaging characteristics that could help identify patients who might develop type A aortic dissection at a diameter less than 55 mm with convenience.
